Deontology

/ˌdiɑnˈtɑlədʒi/noun

Ethics that judges acts by rules and duties rather than by their consequences.

The Greek roots

δέον
déon
that which is binding, duty
+
λόγος
lógos
study, account

Literally: study of what must be done

The story of the word

Jeremy Bentham coined the word, and his Deontology was published in 1834, two years after he died and with his sceptical editor's hand all over it. The irony is thorough: Bentham was the founder of utilitarianism, and the term he built now names the school that stands against him, Kant's position that some acts are forbidden whatever good follows. δέον is the neuter participle of the impersonal δεῖ, it is necessary, so the word literally studies the must.
